Abstract
A machine case comprises a body, a machine case power supply, a light emitting diode, a battery, a driving circuit, a switch and a charging circuit. The light emitting diode is arranged on the body so as to illuminate the inside of the body when emitting light. The driving circuit is arranged between the battery and the light emitting diode and used for enabling the light emitting diode to emit the light when the battery outputs power to the driving circuit. The switch is connected between the battery and the driving circuit and used for selectively outputting or not outputting the voltage of the battery to the driving circuit. The charging circuit is arranged between the machine case power supply and the battery and used for charging the battery when the machine case power supply outputs voltage. According to the machine case, when the switch is pressed down, the light emitting diode is enabled to start working so as to illuminate the inside of the machine case.
Description
Technical field
The present invention relates to a kind of cabinet.
Background technology
When mainboard or hard disk, internal memory etc. break down, often need to open computer cabinet to check or to change, yet cabinet is all generally to be placed under desk, do not put under desk even if be not, owing to opening cabinet, often only can open a side plate, at this moment relatively darkness just in cabinet, be not easy to see clearly, make troubles to our operation.
Summary of the invention
In view of above content, be necessary to provide a kind of cabinet with illumination functions.
A kind of cabinet comprises:
One body;
One chassis power supply;
One first light emitting diode is arranged on body, to illuminate body interior when luminous;
One battery;
One drive circuit is arranged between battery and the first light emitting diode, is used for making during to driving circuit at the battery out-put supply the first lumination of light emitting diode;
One switch is connected between battery and driving circuit, is used for optionally the Voltage-output of battery or does not export driving circuit to; And
One charging circuit is arranged between chassis power supply and battery, and being used for is the battery charging when the chassis power supply output voltage.
Above-mentioned cabinet is not when needing to be opened, as long as do not press switch, light emitting diode is not worked.And at this moment, if computer is in running order, chassis power supply can charge to battery by charging circuit.When needs are taken the cabinet operation apart, just can press switch, at this moment, light emitting diode is started working, to illuminate cabinet inside.

Embodiment
Below in conjunction with accompanying drawing and better embodiment, the present invention is described in further detail:
Please refer to Fig. 1 and Fig. 2, cabinet of the present invention comprises a body 10, some light emitting diode D1, a battery 18, a charging circuit 12, one drive circuit 16 and a switch SW 1.
Described some light emitting diode D1 are arranged on body 10, are used for illuminating cabinet inside when luminous.
Described charging circuit 12 is connected between the 5V standby power supply output pin of battery 18 and chassis power supply 15, is used to battery 18 chargings.
Please continue with reference to figure 3, described driving circuit 16 comprises a chip U1, capacitor C 1 and C2, a resistance R 1, an inductance L 1 and a diode D2.The first pin IN of described chip U1 is connected with the positive pole of battery 18, also is connected with the second pin EN of chip U1 by switch SW 1, and the positive pole of described battery 18 is also by capacitor C 1 ground connection.The 3rd pin GND ground connection of described chip U1, the 4th pin LX is connected with the first pin IN by inductance L 1, also the anode with diode D2 is connected, the negative electrode of described diode D2 is connected with the 5th pin CVP of chip U1, also the anode with light emitting diode D1 is connected, the negative electrode of described light emitting diode D1 is connected with the anode of another light emitting diode D1, and the negative electrode of this another light emitting diode D1 is connected with the 6th pin FB of chip U1, also by resistance R 1 ground connection.Annexation for convenience of description herein, so only mentioned two light emitting diodes, in fact, the present invention can comprise one or more light emitting diode, these some light emitting diodes are connected in series successively or are connected in parallel.The negative electrode of described diode D2 is also by capacitor C 2 ground connection.
When described switch SW 1 was pressed, it is luminous that described battery 18 makes light emitting diode D1 begin by driving circuit 16.For the specific works principle of driving circuit 16, because it has belonged to the technological means that the LED field is commonly used, therefore, in this not go into detail.Certainly, in other embodiments, described driving circuit 16 also can adopt other LED driver modules.
In sum, when not needing to take cabinet apart, as long as do not press switch SW 1, light emitting diode D1 does not work.And at this moment, if computer is in running order, chassis power supply can charge by 12 pairs of batteries 18 of charging circuit.When needs are taken the cabinet operation apart, just can press switch SW 1, at this moment, light emitting diode D1 starts working, to illuminate cabinet inside.
